Kernel for offset angle integration of effective area background model.
- Parameters
-
[in] theta Offset angle from ROI centre (radians).
- Returns
- Integration kernel value.
Computes
\[ K(\rho | E, t) = \sin \theta \times \int_{0}^{2\pi} B(\theta,\phi | E, t) d\phi \]
where \(B(\theta,\phi | E, t)\) is the background model for a specific observed energy \(E\) and time \(t\).
Implements GFunction.
